Near Infrared Spectroscopy And Spiroergometry Testing In Crossfit
Vol.14,No.1(2020)
CrossFit is a young sport discipline which offers varied strength and endurance training through complex exercises. Currently there are relatively few studies focusing on performance analysis in terms of the physiological response in individuals. The aim of the research was to verify near infrared spectroscopy (NIRS) in combination with spiroergometry as a functional means for specific load testing in CrossFit. Elite crossfitter (male, age 20, body height 185 cm, body weight 87 kg) formed part of this study. Two Moxy sensors (placed on the vastus lateralis muscle and the intercostal muscles) and chest (strap) heart rate (HR) sensor were used for obtaining the data. The Cortex MetaMax 3BR2 system was used for portable spiroergometry. The AMRAP method (as many repetitions as possible) was used for testing. The selected test consisted of (1) 10 Deadlifts, 100kg, 15 Assault Air Bike Calories; (2) 12 lunges (with two 20 kg Kettlebell), 10 push-ups, 8 ring swings; (3) 20 SkiErg Calories, 10 50kg back squat, 10 toes to bar. The testing has confirmed that breathing functions and muscle oxidation can be well observed under load in given exercises and movements. It has been confirmed that CrossFit provides a varied load to which the individual must respond immediately. The strength load changes, causing deflection in SmO2 and VCO2 which consequently imposes demands on the respiratory component. This is the first study which monitors the load in the combination of strength and endurance load through crossfit elements. Based on our result, it seems that linking NIRS and spirometry is a suitable combination for a comprehensive analysis of the athlete not only for CrossFit.
